Compare any two graphics cards:
GeForce GTX 780 Ti vs Nvidia Titan X
IntroThe GeForce GTX 780 Ti has core clock speeds of 875 MHz on the GPU, and 1750 MHz on the 3072 MB of GDDR5 memory. It features 2880 SPUs as well as 240 Texture Address Units and 48 ROPs.
Compare those specs to the Nvidia Titan X, which makes use of a 16 nm design. nVidia has clocked the core frequency at 1417 MHz. The GDDR5X memory is set to run at a speed of 1251 MHz on this model. It features 3584 SPUs as well as 224 Texture Address Units and 96 ROPs.
Power Usage and Theoretical BenchmarksBoth cards have the same power consumption.
In theory, the Nvidia Titan X should perform just a bit faster than the GeForce GTX 780 Ti overall. (explain)
Texel RateThe Nvidia Titan X is a lot (about 51%) better at anisotropic filtering than the GeForce GTX 780 Ti. (explain)
Pixel RateIf running with high levels of AA is important to you, then the Nvidia Titan X is superior to the GeForce GTX 780 Ti, and very much so. (explain)
Please note that the above 'benchmarks' are all just theoretical - the results were calculated based on the card's specifications, and real-world performance may (and probably will) vary at least a bit.
Please note that the price comparisons are based on search keywords - sometimes it might show cards with very similar names that are not exactly the same as the one chosen in the comparison. We do try to filter out the wrong results as best we can, though.
Memory Bandwidth: Bandwidth is the max amount of data (counted in megabytes per second) that can be transferred across the external memory interface in a second. It is worked out by multiplying the interface width by its memory clock speed. In the case of DDR memory, it should be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The higher the card's memory bandwidth, the better the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and high resolutions.
Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that are applied in one second. This figure is worked out by multiplying the total number of texture units by the core speed of the chip. The higher this number, the better the graphics card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in one second.
Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics card could possibly record to the local memory in a second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the number of Render Output Units by the the core clock speed. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel output rate is also dependant on quite a few other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to get to the maximum fill rate.
